I worked out that an integer of a little over 200 bits is sufficient
to represent the age of the known Universe in units of the Planck
interval (5.39e-44 seconds). Therefore, rounding to something more
even, 256 bits should be more than enough to measure any physically
conceivable time down to that resolution.

 Why??
 That would not be practical or useful.  The timing of the Big Bang
is not known with great precision; the epoch would be "what we
guessed the time of the Big Bang to be when we standardized this".

Humm... Is the "Big Bang' nothing more than a hyper large and rather local explosion?
